This is without running any frequency scaling at all (no powernod,
cpydyn, or cpufreqd), and also without spinning down the hard drive.

I can't tell about powernod, but the author of cpudyn is a friend of
mine and he did it because he didn't like cpufreqd. I am using cpudyn
on my G3 800 MHz rev 2.2 and it works fine (with laptop-mode tools).

Hi all.

I'm having same problem with my iBook G4. Now with kernel 2.6.9 fan is
almost always running. I've looked at cpu heat and is over 50, normal
53-54 degrees. I'd like to know if it's posible to set cpu limit to 55
in order to fan stops. With OSX fan runs almost never doing same things
(mail, browser, editor, etc) as in Linux. I don't know if setting cpu
limit to a higher value would be a problem, I don't like to fry my
iBook.
I remember that with previous kernels it was different and fan only ran
from time to time.
